Question

Please help me on all the questions thanks !!!!!!!!!!!!!!!!!!

Answer 1

`3x-17=4\\ 3x=21\\ x=7\\\\ (x)/(20)-41=59\\ (x)/(20)=100\\ x=2000\\\\ 3(2x+7)-3x=18\\ 6x+21-3x=18\\ 3x=-3\\ x=-1\\\\ -2(5-x)+16=-14\\ -10+2x+16=-14\\ 2x=-20\\ x=-10\\\\ 2x+4\leq20\\ 2x\leq16\\ x\leq8\\\\ 21-9x\geq-6\\ -9x\geq-27\\ x\leq3\\\\ 144\geq-12x\\ x\geq-12\\\\ (x)/(8)<-12\\ x<-96\\\\ (3)/(8)x=6\\ x=16\\\\ -(5)/(6)x=10\\ x=-12\\\\ 22-(2)/(3)x=14\\ -(2)/(3)x=-8\\ x=12\\\\ -(7)/(8)x+13=-29\\ -(7)/(8)x=-42\\ x=48`


`(3)/(2)x+(1)/(5)=(3)/(4)\\ 30x+4=15\\ 30x=11\\ x=(11)/(30)\\\\ x-(2)/(6)=(2)/(3)\\ 6x-2=4\\ 6x=6\\ x=1\\\\ -(4)/(5)x+6=12\\ -4x+30=60\\ -4x=30\\ x=-7.5`
